Metallic bonding is between metal ions in a sea of delocalised electrons. In Aluminum, there are more delocalised electrons and the ions have a higher charge than Sodium. There is a greater force of attraction between the electrons of aluminum because the protons that are pulling on a 3+ ion are stronger than a 1+ ion. Since it requires more force to overcome these forces of attraction, Aluminum has the higher melting point.

What has the higher melting point sodium chloride or aluminum oxide?
aluminum oxide : Al2O3
Which has a higher melting point Sodium Chloride or Ethyl Alcohol?
Sodium Chloride has a higher melting point because at room temperature it is a solid but Ethyl alcohol has already melted, as it is liquid.
What is sodium chlorides melting point?
The melting point of sodium chloride is 801 0C.
What is the melting point of sodium?
The melting point of sodium is 97.8 Celsius.
Does CaO or CS2 have a higher melting point?
CaO has a higher melting point.
What has the higher melting point sodium chloride or aluminum oxide?
aluminum oxide : Al2O3
Which would you expect to have a higher melting point sodium chloride NaCI or aluminum oxide AI203?
The melting point of sodium chloride is 801 0C. The melting point of aluminium oxide is 2 072 0C.
Is the melting point of sodium higher or lower than rubidium?
Sodium has a melting point of 97.72 oC and rubidium has a melting point of 39.48 oC.
Which of following solids would hae higher melting point AlO3 vs NaBr?
Aluminum oxide (Al2O3) would have a higher melting point than sodium bromide (NaBr). This is because aluminum and oxygen ions in Al2O3 are more strongly bonded through covalent bonds, while sodium and bromide ions in NaBr are held together by weaker ionic bonds. Stronger bonding requires more energy to break, resulting in a higher melting point.
Does sodium chloride or phosphorus trichloride have a higher melting point?
The melting point of sodium chloride is 801 0C. The melting point of phosphorus trichloride is -93,6 0C.
Which has a higher melting point Sodium Chloride or Ethyl Alcohol?
Sodium Chloride has a higher melting point because at room temperature it is a solid but Ethyl alcohol has already melted, as it is liquid.
Does salt have a higher or lower melting point than Na or Cl?
Common table salt (sodium chloride) has a much higher melting point than either sodium or chlorine.
Would the melting point of caesium be higher or lower then sodium?
Lower.
What would you expect to have a higher melting point sodium chloride or aluminum oxide?
Aluminium oxide, because it has a very strong giant covalent structure that takes a lot of energy to break.
